A collection of Jupyter notebooks and Python examples for building with the Claude API. Or directly with uv: Notebooks have relaxed rules for mid-file imports (E402), redefinitions (F811), and variable naming (N803, N806). Branch naming: <username>/<feature-description> Commit format (conventional commits): These commands are available in Claude Code and CI:

This is a comprehensive Jupyter notebook cookbook demonstrating Claude's Skills feature for document generation (Excel, PowerPoint, PDF). It's designed for developers learning to integrate Skills into their applications. Beta API Requirements: - All Skills functionality uses client.beta.* namespace - Required beta headers: code-execution-2025-08-25, files-api-2025-04-14, skills-2025-10-02 - Must use client.beta.messages.create() with container parameter - Code execution tool (code_execution_20250825) is REQUIRED - Use pre-built Agent skills by referencing their skill_id or create and upload your own via the Skills API Files API…

AnthropicCLAUDE.mdanthropics/financial-services/CLAUDE.md
Cowork plugins and Claude Managed Agent templates for financial services. Each named agent ships two ways from one source. Run python3 scripts/check.py before committing — it lints every manifest, verifies all system.file / skills.path / callable_agents.manifest references resolve, fails if any agent-plugins/<slug>/skills/ copy has drifted from its vertical-plugins/ source, and rejects non-ASCII bytes in a .ps1 without a UTF-8 BOM. Keep .ps1 files pure ASCII. Windows PowerShell 5.1 — still the default shell on managed Windows — decodes a BOM-less…

A Next.js chat app. assistant-ui renders everything; one Managed Agents session per conversation runs the analyst, and lib/managed-agents/reducer.ts folds each session's event log into the messages assistant-ui renders. The sidebar is the session list. There is no database. Needs Node 22+, @anthropic-ai/sdk 1.0 or later, and @assistant-ui/react 0.14.27 or later (the defineToolkit/Tools API and approvals on useExternalStoreRuntime). Pull exact shapes from the /claude-api skill's shared/managed-agents-*.md docs.

Long-running Node server (Hono): browser chat with a sessions sidebar (useChat → /api/chat) → Chat SDK web adapter onDirectMessage → one Managed Agents session per conversation, where the conversation ID is the session ID (no mapping, no database; the sidebar is sessions.list, transcript replay is sessions.events.list) → a held session event stream (opened with event_deltas token previews, always on) feeds each fragment back onto the same HTTP response while /api/activity streams the tool calls and thinking the page shows as…

A scheduled deployment, not an app: there is no long-running process in this quickstart. agents/daily-brief/ holds six resource files that ant apply reconciles (agent, environment, two memory stores, vault, deployment). ant apply manages the vault container but never its contents, so agents/setup.sh adds the two credentials with ant beta:vaults:credentials create and writes the vault's ID into deployment.md's vault_ids (a deployment takes vault IDs, not a file reference). Each scheduled run is a fresh session: it reads /mnt/memory/preferences/preferences.md (read-only store), reads…

AnthropicCLAUDE.mdanthropics/claude-quickstarts/managed-agents/knowledge-wiki/CLAUDE.md
This directory is a Managed Agents quickstart: it builds a real M&A data room into a knowledge wiki (a versioned memory store) with one dynamic workflow run, and queries it. The runnable artifact is distill_documents_into_knowledge_wiki.ipynb; prompts/ holds the consolidation agents' prompts, the lead agent's prompt and the baseline analyst's prompt, utilities.py the notebook's functions; everything else exists to set that notebook up. When a user asks you to walk them through setting this quickstart up, read skill.md in this directory…

AnthropicCLAUDE.mdanthropics/claude-quickstarts/managed-agents/mcp-server-typescript/CLAUDE.md
MCP server that exposes Managed Agents session primitives as tools. Two entrypoints sharing one tool set: src/server.ts (stdio → Claude Desktop and Claude Code) and src/server-http.ts (Streamable HTTP → claude.ai custom connector). This quickstart creates no agents, so there is no agents/ directory. It needs one environment, created once from environment.yaml (the command is in that file and in README.md). Commands: bun run stdio (Desktop, Code), bun run http (claude.ai), bun run typecheck.

AnthropicCLAUDE.mdanthropics/claude-quickstarts/managed-agents/roadtrip-planner/CLAUDE.md
A Next.js chat built directly on a Managed Agent session: no chat framework, the event log is the app state. Teaches session event streaming (event_deltas), vault credential injection_location, per-session agent_with_overrides, and multiagent coordinator rosters. The planner calls the National Park Service and Windy APIs with keys it never holds, then hands its draft to a second agent for a quick critique. That second agent is an Opus reviewer running as a session thread. 1. Invoke /claude-api first. It loads the…

This file is the runbook for the four poller demos, docker/, docker-memory/, archil/, and openshell/. The five webhook-started providers (cloudflare-containers/, cloudflare-worker/, daytona/, modal/, vercel/) share one agent and one environment, declared in webhook-demo/ and created with ant apply --yes . from that directory. Never run ant apply from this directory: it walks into the poller demos and creates their resources too, and the claude-lock.json it leaves here is then found first by every directory below.

Sentry posts a signed issue / created webhook → src/app.ts verifies it and hands the issue to src/fixer.ts → one Managed Agents session per issue, with the repository mounted as a github_repository resource, the Sentry MCP credential attached through a vault, a dollar budget, the kickoff message in initial_events, and metadata.sentry_short_id as the dedupe key → the agent reads the issue and Seer's analysis through the Sentry MCP server, reproduces, fixes, pushes autofix/<short-id> → it calls…

Scheduled deployment: cron → Managed Agents session → Sentry MCP search and optional Seer RCA → /mnt/session/outputs/TRIAGE_REPORT.md. Sentry auth is a refreshable mcp_oauth vault credential; the sandbox never holds a token. Provisioning is ./agents/setup.sh (ant 2.0 or later, jq, uv): it records the slugs in ignored sentry-config.json, runs ant apply --yes agents environments vaults, which creates the agent, environment, and vault and records their IDs in claude-lock.json, then runs oauth_setup.py when the vault has no credential for https://mcp.sentry.dev/mcp.

This is a GitHub Action that allows running Claude Code within GitHub workflows. The action consists of:
2 projects use a version of this
A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.
At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.
Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.
Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
